Level-Trac LT-210
LT-210
The Level-Trac Model LT-210 Electronic Control Unit is a component of a remote level indication system, as described in ASME Section I, PG-60. The control unit may also be used as an alarm or trip device. Discrimination between water and steam is based on the significant difference in resistivity between the two states over the saturation range. The control unit interprets and displays the signal from up to 12 probes mounted in a probe manifold. Via voltage applied to the probe tip, conduction in the presence of water will occur between the tip and the inside wall of the column. Typically, probes are spaced horizontally in a manifold attached to the steam drum, with each probe connected to its own sensing and water/steam indication circuit. A vertical display of Green/Red indicators provides a simulation of water level in the steam drum. Spacing between probes is per customer requirements to cover the visible range and alarm or trip points.

The Level-Trac Model LT-230 Electronic Control Unit is a component of a remote level indication system, as described in ASME Section I, PG-60. The control unit may also be used as an alarm or trip device. Discrimination between water and steam is based on the significant difference in resistivity between the two states over the saturation range. The control unit interprets and displays the signal from up to 36 probes mounted in a probe manifold. Via voltage applied to the probe tip, conduction in the presence of water will occur between the tip and the inside wall of the column. Typically, probes are spaced horizontally in a manifold attached to the steam drum, with each probe connected to its own sensing and water/steam indication circuit.

Level-Trac Model LT-302
LT-302
Alarm and Trip Logic Each LT-302 control unit is supplied with two DPDT relays for alarm and trip actuation. Each probe has a dedicated DPDT relay to be pro- grammed and used as the application requires. The relays are programmable to be in the ener- gized (failsafe) or de-energized mode as Normal. Normal may be independently programmed as wet or dry, as the application requires. A third relay is dedicated for fault logic. Fault Logic Fault logic is based on an out of sequence scenar- io, alerting the user to a probe or conductor issue. Indication of fault is via a flashing yellow LED and the activation of a dedicated relay. Programming Quest-Tec Solutions will supply the control unit programmed and tested per the user requirements. Each control unit is serialized and fully traceable. Field modification can be performed via solder jumps.

Level-Trac LT-420
LT-420
The LT-420 is a unique device used for water level indication on Section I boilers and other boiler feedwater applications. The unit combines several standard features in order to satisfy modern boiler code requirements, and at same time address challenging aspects of water/steam level applications. ASME BPVC.I-2019 PG-60.1.1 requires a Remote Level Indicator (RLI), to continuously measure, transmit and display the water level in the control room. The RLI is a discrete system that monitors the water level, independent of the DCS. Paired with a GWR transmitter, the LT-420 provides a reliable solution for water level indication.

Level-Trac LT-440
LT-440
The Questtec LT-440 provides an exclusive means of achieving accuracy with Guided Wave Radar, or any other loop powered instrument, when used in a water column to determine level in a high pressure steam system. Water density increases as the temperature of steam condensate decreases. This can create a significant error to the actual water level in the water column as compared to the water level in the steam drum. For example, the density of water in a steam drum operating at 650° F is 599.54 kg/m . The sub cooled water in a water column may be only At 615° F, and have a density of 657.49 kg/m . This would result in an error of 8.9% of the water height in the column as compared to the steam drum. A water column with 30″ of water indicated, could be expected to be nearly 3″ lower than what is actually in the drum. Even an accurate measurement of level at the water column would result in a Water Density Error. The LT-440 utilizes the data collected from at least 4 thermocouples installed on the water column and determines an actual average water temperature. The primary loop is dynamically corrected and a secondary loop is communicated to any device included in the loop.
